To all whom it may concern:

Be it known that I, FREDERICK STEIN- HAUER, a citizen of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Boat-Fastenin -Means, of which the following is a speci cation. l

My invention relate to novel means to connect a boat or the like with a pier, landing or other fixed object.

An im ortant object of thisinvention is to provi e means of the above mentioned character, which will retain a boat or the like in the desired locality while permitting the same to move freely vertically with the termined degree but preventing the same from moving laterally in either direction beyond a certain distance, the lateral movements of the boat being checked by the apparatus in a most advantageous. mannento absorb shocks and jars transmitted to the boat by the waves.

A further object of this invention is to provide means of the above mentioned char-A acter, which will yieldingly oppose the slight lateral movements of the boat in opposite directions.

A further. object of this invention is to provide means of the above mentioned character,- which will prevent the undue longitudinal movement of the boat but permit of the free lateral swingingand recprocatory movement thereof. l

A further object of the invention is to provide means of the above mentioned character, which are simple in construction, strong, durable, cheap to manufacture and easy to connect and disconnect with and from the boat.

Other objects and advantages of this 'invention will be apparent during the course of the following description..

In the accompanying drawings forming a part of this specication and in whichl like numerals are employed to designate like parts throughout the same, Figure 1 is a plan view of my improved connecting means, showin the same in use, Fig. 2 is any end view o the same, and, Fig. 3 is an enlarged detail section through a portion of one of the triangular attac ing elements.

In the drawin s, wherein for the sake of illustration, is s own a preferred embodiment of my invention, the numeral 4; desigconnected brackets4 5,'

Each triangular attaching x element' comprises a longitudinally` extending tube'9 and lof the 'longitudinal tube 9 of the coupling 13 are spaced, as shown.

Mounted toy reciprocate within the longitudinal tube 9 and the guide sleeve 15, as more clearly shownin Fig. 3, is a piston or rod 16, carrying a sleeve 17, clamped thereto by means of a clamping screw or b olt 18, as shown. Surrounding the reclprocatory rod16 and upon opposite sides o the sleeve or' ring 17 aresuitably stiff compressible and eXpansible coil springs 19, the outer ends of which engage the guide sleeve 15 and the coupling 13', as shown. The reciprocatory rods 16 are provided at their outer ends `witheyes or apertured heads 20, which receive bolts or pins 21, carriedby upstanding brackets ablyv attached to the forward and rear ends nates a pier or wharf, to whichare suitz'iblyY provided wfithf'eyesY Vor loops 6,' recelving transverse endj por!v Y tions 7 oftriangular attaching elements 8'.Y

22, preferof a boat 23, as'shown. The free ends of.

the bolts or pins .21 are apertured for recelvmg-pad-locks' 24:- or the like, whereby the boat is securely connected or locked with the reciprocatory rods 16.

In the use of the apparatus, it is obvious .that each of the attaching elements 8 may be swung in avertical plane and moved horizontally a restricted distance in either direction, whereby the bolts or pins 21 may be easily passed into the openings of the eyes or apertured heads 20. It is obvious that the brackets 22, which are preferably rigidly attached to the boat, are pivotally connected with the rods 16, whereby the boat 23 may swing laterally in either direction. When the boat is reciprocated laterally in either direction, or swung laterally beyond a certain degree, either set of the springs 19 will be compressed, to oppose such movement, depending of course upon the direction of the same. By these means the shocks imparted to the boat by the waves are absorbed with the least damage to the boat.

The apparatus holds the boat in its normal position, and prevents the same from turning around or moving longitudinally beyond a certain degree. In addition to the secure manner in which the apparatus will hold the boat in place, the same may be uickly connected and disconnected with and trom the boat. When the boat is disconnected therefrom, the attaching elements 8 may be swung upwardly upon thev pier 4.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without. departing from the spirit of the invention or the scope of the ment of the rods in both subjoined claims.

Having described my invention,I claim 1. In apparatus of the character described, the combination with a relatively stationary object, of a plurality of spaced triangular open relatively rigid attaching elements, means pivotally connecting the attaching elements with the relatively stationary object, so that such elements may be swung in a substantially vertical plane, reciprocatory rods earned by the attaching elements, means to yieldingly op )ose the moveirections, and means to connect the rods with a boat.

2. In a boat securing apparatus, tle bination with a relatively stationary object, oi a longitudinal tube, means pivotally con- Comnecting the longitudinal tube with the relatively stationary object, so that the longitudinal tube may be swun in a substantially vertical plane, a gui e sleeve spaced from the free end of the longitudinal tube and rigidly connected therevvlth, a reci rocatory rod mounted Within the longitu mal tube and guide sleeve, a sleeve rigidly connected with the reciprocatory rod .and disposed between the guide sleeve and the longitudinal tube, coil springs surrounding the reciprocatory rod upon opposite sides of the sleeve carried thereby and engaging said guide sleeve and the longitudinal tube, and means to connect the reciprocatory rod with the boat.

3. A boat attaching apparatus, comprising an open tubular frame, a relatively stationary object, means pivotally connecting one end of the open tubular frame with the relatively stationary object, a reciprocatory rod mounted Within a portion of the open tubular frame, spring means to oppose the movement of the rod in both directions, and means to connect the rod with the boat.

l. A boat attaching apparatus, comprising a tube, a relatively stationary object, means pivotally connecting the tube with the relatively stationary object, a rod mounted to reciprocate wit in the tube, spring means to oppose the movement of the rod in both directions, and means to pivot-ally connect the rod with the boat.

In testimo-n whereof I aix my signature in presence o two Witnesses.
